Modded Brawl Character Colors

Description

TODO: Reference rendering here.

Some Brawl Modded Characters seem to have issues with a change to an uninitialized shader color. Regression happened in 4.0-8388 - https://dolphin-emu.org/download/dev/de21da5fb25446a68c2bb79400c4935dfdbbbaa2/

Prior to that build, this renders correctly. In latest builds, blaziken has no color, and is blacked out.
